T (ZZZ whom it may-concern:

Be it known thatI, CHARLES W. QBCRYSON, a citizen "of the United States, residing at Cleveland, in the county of Cuyahoga and 6 State of Ohio, have invented a certain new and useful Improvement in Sand-Mixing Devices, of Which the following is a flill, clear, and exact description, reference being had to theaccompan'ying drawings. V

This invention-relates to sand mixing machines'of'a type adapted to be moved "over the sand thrown-in 'ej-pile or iridge *on the floor and the general -object ofthe invention is to provide a simple, "efficientmachine for thoroughly manipulating, working-and mixing of th'esand, wher'ebyit is lightened and its ingredients blended. "A morespec-ifio' ob-v ject of'the invention is tb iprovid'e a machine, adapted "to move over "sucha pile or ridge by suitable propellingmeafis,"and ha'iringrotary mixing device's providedwith blades adapted to engage the sand and mix for l'rnea dit and throw it rearwardly relation to direction of travel of theinach'ine. y In devices hretofore'u'sed it'hasjbeeh ci1stomary to provide kneading devices 'on; 'a horiiontal axis and in the use 'ofwhich difficulties'are encountered in attempting'ito treat the pile entirely to its base, particularly in that thesand is unduly siiattered. l

This invention contemplaftesarranging kneading devices on avertica-l axis "and having the blades extended substantially upright and revolving about such axis as the truck'moves over'the ipile; whereby the entire pile may be treated without difiiculty and the sand 'mhy' be tossed to a certain extent through the air "and at the same timeleave it in a narrow ridge or pile substantially as before the "machine passed over it.

My invention contemplates (the use. ef

various adjustments "in the machine, as for example, vertical adjusting of mix'ingdevices "so they may come nearer the bottom of the pile or be lifted somewhat above thesame if desired. This present invention v is more fully described connection with the accompanying "drawings and the "essential characteristics ar summarized in the claims. a V y In the drawings Fig. 1 is "a side elevation of my sand mixer; 2 is a plan "hi the same; Fig. 3 isthe end elevation io'oking forwardly from the rear end of the-sand mixer. r

Describing the sand-mixer as shown'by use of referencecharacters to designate its;

parts, 1 and. 2 indicate respectively-for ward and rear upright members ofZa.git'rame The frame-just described maybejof any 7 suitable construction; it is gpreferably, supported on four wheels, theforward, wheels Sjbeing steering wheels, whi-lefgwheels 9 are driving wheels. The ,wheels '8 "are shown as carried -'ofn swiveled -"axle.' members 10, embracing vertical extensions 11 ;of l the frame members '1, While forwardly extending arms 12 are pivotTallyf connected by links with a rock arn'i 1 5 at-the'lower end ofilthe steerin ""column '16, shown as carrying asuitab'le "steering Wheel 18.

v. The driving of the-vehicle may be accomplished in any suitable manner, for example, I have shown an electric-motor 20, havinga sprocket 21, driving ;a sprocket. chain "22, running over afsprocket wheel 24:, l'ilgidfQF-ll the "rear axle 25,- which is in turn rigid the wheels '9. l he electric power tor the motor -20 may besuppliejd either by the bat: teiies carried by the frame or by asuitable flexible lead wirewhere thj'e vehicle h-as -a short region of travel, -or bytro'lley if de: sired. r 1 r The sand mixers proper areshown a g qm prising drums 3050f any Sultfllblfi construe tion adapted to rotate about avertical is and provi-ded withradial plates blades of .the opposin-g drums slightly la-p, as the drums rotate inop'posing e9; tions. It is desirable to havethese dr ns vertically v adjustable. Acflolfd-ingly shaft s 33, on which the; drums [are carried are mounted in bearings 34,; oar'ried b qcross members 35 of va frame adjustably supported by the main frame, the cross member being intermediate of the ends'of the frame and shown as connected with longitudinal channel members 36, which are braced near their ends by transverse members 38, The members 36 rest against the inner sides of the uprights 1 and 2 and bolts 4:0,connecting these members extend through vertical slots 41, in the uprights to allow vertical adjustment while allowing the frame carryingthe mixers to be securely held in any desired position.

The raisingand lowering of this frame may be accomplished by any suitable means, as for example, vertical racks rising from the members 38 and rigid therewith and which are engaged by pinions 46, on longitudinal shafts 48, intermediately connected by a sprocket chain 49 running over spockets 50 on the ends of shafts 48, whereby a suitable handcrank 52 may be used'torotate both shafts and raise the frame evenly. On the upper ends of the shafts 33' are bevel gears 60, driven by pinions 62' on a shaft 64, having suitable bearings 65,carried on the framemember 36. The "shaft 64 maybe driven by a sprocket wheel 67' over which runs a chain shown at 68, in turn driven by a pinion 69 on the armature shaft of motor 70; I v 7 It will be seen that the arrangement of the pinions'62 on the shaft 64: causes the drums 30 to rotate in oppositedirections, preferably that shown by arrows in Fig.- 2', whereby the inner sides of the'drums move rearwardly with the relationto the move- -ment of the truck. If desired, however,

the motor 70 maybe reversible and the truck maybe run in opposite directions, so that arrows in Fig. 2. 1 Thus the ridge of sand is' direction ofthe drums may be such that the inner sides move rearwardly with the relation to the direction of movement of the truck, irrespective of whether the truck'is passed through between the drums by means of blades 32'th'ereon and thrownrearwardly. By regulating the speed of these drums the sand may be thrown into a pile or ridge of substantially the 'same height and size as before, whereby this process may be indefinitely repeated by running the truck forwardly and back over'the samcwithout manually handling the sand. lnFigs. 1 and 3 the'drums are shown as raisedsomew'h'ati'abovethe floor, as may he sometimes desirable, but by adjustment of'the frame carrying the drums they may be raised or lowered to work only theupper portion of the ridge or pile of sand, or to work the entire pile substantially to the floor.

Having thus described my invention, whatl claim is: i V

1. In a sand mixing machine, the combination of a vehicle adapted to move over a pile of sand, intermeshing paddle Wheels carried by the vehicle, the-blades of said paddle wheels having substantially flat impacting surfaces and means 'for rotating said paddle wheels as they are, advanced through the sand, whereby the latteris thoroughly kneaded and mixed and left in substantially the same character of pile as before the operation. w

.- 2. In a sand mixing apparatus, the com:

bination of a vehicle adapted to move over a pile of. sand,'coopera ting rotary elements carried by the vehicle and having radial projecting blades thereon, in intermeshing engagement and having-substantially fiat impacting surfaces, and means for rotating these-elements on vertical axes, so that the blades move in the same direction at the inner side of each element, whereby .theblades are thrust into the sand by movement of the vehicle and the sand is pressed together with a kneading action as the blades approach and is further-cut as the blades of one elementpass those of the otherelements,

said rotary elements leaving :the sand in 4; In a sand mixing apparatus, the come bination'of a vehicle body, a rectangular frame mounted therein, cooperating paddle wheels on vertical axes intermediate the ends of said frame, and interconnected geared shafting coacting with verticalfrack bar s adjacent to thefcorners of the frame,-

whereby the'height of the paddle wheels may be varied. 1

5. In a sand mixing machine the combination of a vehicle body, a frame supported horizontially therein, sand vmixing members comprising intermeshing vertical blades mounted intermediate the ends of'said framepand means forfraising and lowering said frame comprising shafts on said body parallel with the side. members. of ,said

frame, having gears in meshing engagement with re cl: bars on said frame.

6. In apparatus of the class described, the combination of a vehicle body, a frame mounted therein, vertically arranged paddle Wheels mounted intermediate the ends of said frame and rotatable in opposite directions, means for adjusting the height of said frame, said means comprising rack bars extending vertically upward from the corners of said frame, horizontial shafts mounted on opposite sides'of said body having gears meshing With said rack bars, and means connecting said shafts whereby the frame may be raised or lowered evenly.

In testimony whereof, I hereunto affix my signature.
